What Is the WhatsApp Blast Task?

The WhatsApp Blast task requires you to extract phone numbers from college groups or your personal connections and use a bulk-messaging tool to send out your campaign message, typically a form for career guidance or program enrollment. The goal is to achieve either 50 responses or 3 enrollments. This task is worth 1000 points and 20% weightage in your evaluation.



Step-by-Step Instructions


1. Start the Task

• Log in to your dashboard and select Start Task in the WhatsApp Blast section.

• Review the criteria (50 responses or 3 enrollments) as shown on the task card and submission window.


2. Extract Phone Numbers

• Collect phone numbers from your college group, network, or use an aggregation tool.

• Save these numbers in a spreadsheet (Excel or CSV) for easy import later.


3. Download and Install Pro Sender Extension

• Go to the Chrome Web Store or trusted provider and search for the Pro Sender extension.

• Click Add to Chrome and confirm installation. No extra software is needed—just the browser extension.


4. Set Up Pro Sender for WhatsApp Blast

• Open WhatsApp Web in your Chrome browser.

• Click on the Pro Sender extension icon in the browser toolbar.

• Import your contact list by uploading an Excel/CSV file or enter numbers manually separated by commas.

• Craft your message (form link, invitation, or program details). Personalize with names or other variables if desired.

• Attach images, PDFs, or other files if needed.


5. Configure Sending Options

• Set up batching or time intervals to avoid spamming too quickly (helps prevent WhatsApp bans).

• Check the message preview, verify correct mapping of names/numbers, and run a small test batch for quality control.


6. Blast the Message

• Click Send and keep WhatsApp Web open during this process. Pro Sender will send each message individually, ensuring privacy and avoiding bans.

• The extension allows for personalized messages and attachments, increasing engagement.


7. Monitor Response and Enrollments

• Track incoming replies, form submissions, or enrollments.

• Collect engagement data in your spreadsheet for reporting.


8. Submit Student Details and Blast Proof

• Enter the total number of enrollments in the submission field on your dashboard.

• List each student’s name and phone number who enrolled; add more students if necessary.

• Upload your spreadsheet with phone numbers as CSV or PDF to verify activity; attachments up to 50MB are supported.

• Click Submit Task when complete.


Tips for a Successful WhatsApp Blast

• Use clear, concise language and personalize each message for better response rates.

• Include a call-to-action and ensure your form link works on mobile devices.

• Avoid sending identical messages too quickly—use batch settings and intervals.

• Track responses and follow up with interested students.


Why Use Pro Sender?

• It does not require recipients to be in your WhatsApp contacts, making it ideal for mass outreach.

• You can schedule, customize, and send messages in bulk from WhatsApp Web with attachments.

• Real-time updates and delivery reports help monitor campaign effectiveness.
